Thanks for the congrats man.

I might ditch the SR55 - who knows... Won't be sure if I want to keep it until I get it tuned. If it under-achieves I will probably look for alternatives. Honestly though, it feels as though it's going to be pretty darn responsive. If it's responsive and puts out more power than a green then I probably will keep it... At least for a while until the power bug bites me. I got such a darn steal on the turbo I might as well run it for at least a little bit to see what she's got.

I'm up to 75 miles now. All is good.

I'll probably stop doing mile by mile status posts now.

As of today how is it holding up? Whats your review on it now?

SilverSurfer · 07-09-2007, 07:40 AM

This was a great engine the time I owned it. I sold the car in March and as far as I know the buyer is still using the engine and loves it. Last time I had an email exchage with him was a couple months ago.

CenCali07STI · 07-09-2007, 06:07 PM

so what did your numbers end up being with the sr55?

SilverSurfer · 07-10-2007, 03:13 AM

Numbers were decent for that turbo. On a very, very conservative tune on the Buschur mustang dyno the car put down 342 whp and 330 wtq. This sounds low, but a stock STI only puts down 220whp on that dyno.

I was going to do another tune with pump & race gas and higher boost, but I sold the car before getting a more aggressive pump gas and race gas tune...

dang i was about to ask why is there so many ppl building engines just to sell and lose their ass. but after seeing those numbers i would sell too. what psi was 342 whp at?

It probably has more to do with the fact that APS turbos have consistently underperformed. Plus a mustang dyno is the lowest reading dyno.

this is why i ask about the psi, with the sr55 i had i was making 350whp @ 21 psi on a mustang on a completly stock internal 2.5.

I wasn't interested in impressing people with dyno numbers. The plan was to do an ultra conservative pump gas tune and then wait about 4-5 months and go for bigger power on both the pump gas and race gas tunes.

A guy made around 360 whp on that dyno with a rotated GT30R turbo. I'm sure with more appropriate pump gas tune I would have made that much or more. It's just a low reading dyno. That's a pretty good comparison of around about what the turbo should be making since it's a GT30R center section bolt on.

Buschurs dyno is a very very low reading dyno. Those numbers are not bad at all for a conservative tune on that dyno and boost. Easily a mid 11 second car with those numbers on that dyno.

I don't think this is a case of a aps turbo not working well, although many times it is the case.

Also forged internals don't give you power, they give you longetivity and strength, the heads would help a fair amount though.

yeah the internals are in support of the cams/headwork and everything that adds power

Getting forged rods and pistons do not increase power.
